[libvirt-users] network problem



Hi,

i have a lvm partition that i need to share from the host server to
the virtual machines.

em1: 10.0.0.251
em2: 10.0.0.252

macvtap:em1 10.0.0.249
macvtap:em2 10.0.0.250


With identical configs (so i believe that they are) from VM win2003 i
can ping to all the above IPs and open the samba share as a map drive.

>From VM: win2008 i can ping to VMwin2003 but not at hosts IPs .251 & 252.

I have attached some info on my setup.

Plz advice.
